Distributed Energy Resources (DER)
such as photovoltaic (PV) systems and battery energy
storage systems (BESS) can be operated collectively as
microgrids. Microgrids can be effective in meeting local
load requirements as well as in improving the power
quality and stability in a modern power distribution
system. Multiple microgrids can also be operated in a
coordinated manner as a cluster, to improve the
resiliency of the power distribution system. In the event
of an outage caused by a transmission system failure, the
microgrids in a cluster can use their distributed
generation capacity and energy storage resources to
recover and extend power availability to the critical
loads in the system. In this paper, an illustrative cluster
of two microgrids based on the IEEE 13-bus model with
DERs has been used, to demonstrate the operation of the
concept using real-time simulations. Using real-time
simulations, capabilities such as switching
reconfiguration following faults, identification of
optimal DER placement for effective power quality
management, and power electronic controller validation
have been demonstrated. For the two-microgrid cluster,
this paper also presents improvements in load voltage
quality and
